To all whom it may concern:

Be it known that I, SAMUEL YEANEY STooK- and useful Improvements inWelt-Cutting Machines; and I do declare the following to bea full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in machines for cutting leatheror other'm'aterial into welts or strips for use in the manufacture ofgloves, mittens, pocket-books, and other leather goods. I w

The object of the present invention is to provide a machine of thischaracter which will vention consists of certain novel features of besimple in construction,-durable in use, efiicient in operation, andcomparatively inexpensive to produce.

With this and other objects in view the inconstruction, combination, andarrangement of parts, as will be more fully described, and particularlypointed out in the appended claims. I

In the accompanying drawings, Figure 1 is a side elevation of theimproved machine.

Fig. 2 is a top plan view of the same, a ,portion of the machine and theleather upon the machine being broken away to show the cuttingapparatus. Fig. 3 is a Vertical longitudinal section through themachine. Fig. 4 is a vertical transverse section taken on the line 00 wof Fig. 3.

In the embodiment of the invention illustrated in the drawings thenumeral 1 denotes a suitable frame or support having journaledtransversely at one end a roller 2, upon which the continuous web orsheet of leather or other material A, to be cut into welts or strips, iswound. From the said roll 2 the leather A passes up over a guide-roller4, journaled.

ber of said cutting-disks may be provided, they maybe spaced anydistance apart, ac-" cording to the number and size of the welts intowhich it-is' desired to cut the sheet of leather. The cutting of theleather is eflected' by the tension exerted upon the same' as it is; 1passed around the cutter, and. this tension is' 1 produced by providingcombined guide and" tension rollers 9 and 10 for theleather before itpasses to the cutter anda series or group 11 of guide and tensionrollers after it has been cut into welts or'stripsB by thecutter. Tli'erollers 9 and 10 are" transversely disposed across the frame above andin rear of the cutter, and they are journaled in inclined uprights 12,secured upon each side of the frame.

The web or sheet A of leather after leaving the roller t passes underthe roller 9, then up over and around the roller 10, and then around thecutter, as seen in Fig. 3. In .order to more effectively hold theleather against the cutter while it is being cut, a spring-plate 13,secured upon a cross-bar 14;, is adapted to bear upon the leatherslightly above the cutter, as shown, and in order to prevent the leatherfrom shifting sidewise a comb-bar 15 is secured transverselyto the frameon each side of the cutter. The teeth 16 of thesecombs project betweenthe cutting-disks 7 to hold the leather againsttransverse movement, aswill be readily understood. The group 11 of transverselydisposed rollersbetween which the welts B are passed after being formed by the cuttercomroller 18, and two idler tension-rollers 19 and 20, one of the latterbeing disposed on each side of the positively-driven roller 18. Thewelts B pass between these rollers, as shown in Fig. 8, and then betweenone or more groups 21 of separating-rollers. Each one of said groups 21separates one welt or strip B from the body of welts or strips andconsists of a positivelydriven roller 22 with one tension-roller 23 uponeach of its sides. It will be understood that as many of these groups 21are provided as. the number of welts into which it is desired to cut theleather.

In order to drive the cutter, a main shaft prises a guide-roller 17, apositively-driven tion of the frame 1, and said shaft is geared to thecutter-shaft 6 in any suitable manner, but preferably by an endless belt26, which is passed about pulleys 27, secured upon said shafts 26 and 6.In order to drive thevarious other rollers, a transverse shaft 28 isprovided and geared to the shaft 25 by a belt 29, passed about pulleys30, secured to said shafts 25 and 28. The roller 18 is driven by a belt31, passed about pulleys 32, secured to the shaft 28 and the shaft ofthe roller 18. shafts ofeach two adjacent rollers 22 are geared togetherby belts 33, passed about suitable pulleys 34C, and the shaft of theinnermost roller 22 is geared to the shaft 28 by a belt 35, which ispassed .around pulleys 36, secured to said shafts, as clearly shown inFigs. 1 and 2.

The operation and advantages of the invention will be readily understoodfrom the foregoing description, taken in connection with theaccompanying drawings. It will be seen that when the sheet or web ofleather is properly placed in the machine, as in Fig. 3, and motion isimparted to the main drive-shaft 25 the cutter and the various rollerswill be set in motion through the belt-gearing previously described. Themachine may be constructed to cut any number and any size of welts andwill work equally well on all kinds, weights, and grades of leather.Owing to the capacity of the machine and the fact that it may beoperated by one man, a great saving in time and labor is effected by itsuse.

It will be understood that various changes in the form, proportion, andthe minor details The of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages ofthis invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. A welt-cutting machine comprising tension-rollers, apositively-driven roller having a plurality of rotary cutters, spacedapart, means to draw the welts cut by the cutters .from the said roller,said means including a positively-driven roller and tension-rollerscoacting therewith, and delivery means for the several welts. each ofsaid delivery means including a positively-driven roller and atension-roller coacting therewith, substantially as described.

2. In a machine of the character described, the combination of asuitable frame, a rotary cutter mounted thereon, tension-rollers adaptedto guide the material to be cut, to and from said rotary cutter, aspring adapted to hold said material upon said rotary cutter, and acomb-bar eoacting with said rotary cutter to prevent transverse movementof the material upon the said rotary cutter, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
